'CARDING -MACHI NE.

SPECIFICATION forming part of Letters Patent No. 630,479", dated August8, 1899.

Application filed April 19, 189.9.

To all whom it may concern:

Be it known that I, SAMUEL BERAN, constructor of looms, residing inBriinn, Obrowitz, in the Empire of Austria-Hungary, have invented newand useful Improvementsin Oarding-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the same.

The purpose of the present invention is a carding-machine in which theinferior and shorter material left behind upon the cylinder by thedoffer is taken off by a system of card-covered rollers underneath thedoifer which are connected with the cylinder and is vigorously cardedand mixed with the material taken oif by the doffer, the mixture beingagain submitted to a further carding process.

In the accompanying drawing is illustrated a cardingmachine providedwith the arrangement referred to, the construction and workin g of whichin other respects are Well known.

The system of card-covered rollers referred to consists of a worker eclose to the cylinder,- which takes off the short material left on thecylinder (1 by the dofier b and cards it in con junction with theclearer f. The latter, f, carries the material to the auxiliary cylinder9, where it is again worked by the cards of the two rollers f and g.Above the clearer f there is a beater d, which, having raisedthe nap ofthe material on the cylinder a before being taken off by the worker e,acts upon the auxiliary cylinder 9 and in connection with the latteroperates again upon the material taken up by the cylinder g, by whichmeans a good streak is given to it, which is absolutely necessary forthe formation of a uniform sliver.

At the surface of contact of the doffer b erial No. 713,571. (No model.)

and auxiliary cylinder g the material taken up by them (I) and g) isintimately mixed and the mixture well carded, so as to leave the surfaceasa uniform and homogeneous fleece as it is taken off by the doifer-combto be condensed into a sliver.

The object of the dust clearer f, placed before the surfaces of contactof the doffer b and auxiliary cylinder 9, is to separate the inferiorfibers carried along by the dofler b and auxiliary cylinder g.

It is evident that in the arrangement here described another series ofworkers, such as e, and clearers, such as], may be interposed betweenthe clearer f and auxiliary cylinder g.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is In a carding-machine, the combination with the cylinderat and the doffer b, of a system of card-covered rollers e, f, 9connecting the doffer with the cylinder at, which subjects the materialnot taken off by the dofier to a carding process, an auxiliary cylinder9 cooperating with the doifer b to mix the material intimately with thatfirst taken off by the dofier and operate again upon it, and a beater dwhich 011 the one side raises the second material on the cylinder abefore the carding process, and on the other side gives to it a goodstreak on the auxiliary cylinder g.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
